What does an ENERGY STAR score of 46 mean?

BuildingCensus bands the score into report-card grades; 46 falls in band D — lowest band (1–54). It sits 29 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 24535 Owners Inc.'s 95.4 kBtu/ft² across 88,322 sq ft works out to about 8.4 billion Btu (2,469 MWh-equivalent) in 2024. Its source EUI of 128.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
